S4 B8.5 Electrical issues

[Ajwhite]

First time this has happened, driving home tonight. Start the car up and Parking Brake, TPMS malfunction.

On the drive noticed, start stop malfunction, outside temp sensor not working.

Parking up, parking sensor malfunction....


All at the same time on the same drive home. Any ideas?

Sounds like electrical issue, battery or alternator.

What fault codes do you have?

I don't have a code reader, but drove yesterday and all faults have gone. Driven today and all perfect

How old is the battery? Seemingly unconnected errors often occur when the voltage gets too low.

Also read somewhere it can be due to the Abs sensor too?

I'll check but I don't think it's ever had a new one

Just found this thread too, sounds very similar to my issue

HELP!! ABS/ESP, PARKING BRAKE FAULT AND HEADLIGHT RANGE CONTROL DEFECTIVE!!

Hi guys, as the title reads I seem to have a big problem, I hope to god its not the ABS module! To start, my Audi a4 2.0tdi 143 B8 has been sat for the last 5 days and the day before yesterday I just started the engine to turn it over and everything was fine. However tonight I went to take it...

Solved:

Error code relating to my Instrument cluster, it's pretty intermittent but nothing to do with a speed sensor

Going to see how it gets on and fix when needed

That could also be related to a wheel speed sensor for the abs I think which causes loads of errors to come up.
